Washtenaw Impressions is published 7 times per year (September, October, November, February, March, April, May). It usually includes an article about the current exhibit at the museum, a detailed description (or transcript) of the last program, numerous pictures, and a list of other historical happenings in the county and beyond. The Washtenaw County Historical Society has archived issues of the Impressions dating back decades. The issues are locked away in the museum, but one should be able to view them upon request.
An index to Washtenaw Impressions from 1943-1985 was produced for the Internet by Jan E. Tripp.
